Application filed April 22, 1909. Serial No. 491,486.

To all whom it may concern: like conditionsas to pressure etc., is the area lie it known that I, NILFRED SHURTLEFF, of the opening 9 or 10 which may be una citizen of the United States, and a resident covered by the valve. When the shell is in of Moline, in the county of Rock Island and the position shown in Fig. 1 such measure State of Illinois, have made certain new and is the area of the opening 9, and when the useful Improvements in Valves, of which the shell is reversed the measure is the area of following is a specification. the opening 10. The boss is internally My invention is an improvement in valves, threaded, and the threads are engaged by and consists in certain novel constructions the threaded portion 15, of a stem 16, of the and combinations of parts, hereinafter de- Valve 18, which is movable in the shell or scribed and claimed. sleeve 8. The free end of the stem 16 is The object of the invention is to provide provided with a handwheel 17, and a packa valve, especially adapted for use with mg nut 18 encircles the stem and engages vapor heating apparatus for controlling the h nut 11 befOIe mentioned.

It will be observed larged, without the use of special tools. that all of the valve operating parts are car- Rcferring to the drawings forming a part fled by the nut, and are removed and rehereof, Figure 1 is a longitudinal section p a d e e tht 111 be not ed' rom of the valve, and Fig. 2 is a perspective view F g- '1 that h as g S n g d nnularly of the reversible shell or leeve, as at 20, around the sleeve, SO that'it is not.

The embodiment of the invention shown e e s ry t0 ahlle t p ni g 9 and 10 in the drawings, consists of a substantially Wlth the Outlet- 7 cylindrical casing 1 of general T-shape, hav- I claim ing an end inlet 2, and a side outlet 3. A A device 0 the Class e ri e I diaphragm 4, is arranged between the body prising a substantially cylindrical casing of the valve casing and the inlet 2, and the having at one end an inlet, and at the side an diaphragm is centrally perforated as at 5, and outlet, a fperforated diaphragm separating provided with an annular flange 6 encircling the inlet rom the body of the valve, an anits opening and forming a valve seat, and exnular flange encircling the perforation oftending into the body portion of the casing. the diaphra and forming a valve seat, a A shoulder 7-is formed between the flange sleeve seate on the diaphragm and encirand the diaphragm, and a sleeve or shell 8 cling the seat, said sleeve having at each .end

encircles the flange, the. lower end of the an opening one of which is of greater diamsleeve resting on the diaphragm, with the eter than the other, a valve slidable in the inner edge engaging the shoulder, sleeve and cooperating with the seat, and

The shell is provided near each end with means for limiting the opening movement of anopening 9 and 10, and the opening 9 is the valve to prevent said valve uncovering of greater diameter than the opening 10, its upper opening, and a nut threaded into one of he said openings forming the comthe casingand carrying the valve, said nut munication between the inlet 2 and the outbeing of greater diameter than the sleeve to let 3 of the casing. The shell is retained permit the removal thereof, and engaging in position by a nut 11 threaded into .the the end thereof to retain it in position. end 12 of the. casing directl opposite the '2. A device of the class described, cominlet 2, the nut being provide with a lateral prising a casing provided at one end with annular flange 13 engaging the end of the an inlet, and at 1ts side with an outlet, a percas ng, and with a central boss .orhub 14; forateddiaphragm between the-inlet end The boss 14 is adaptedto engage an enlargeand the'body of the casing, a sleeve resting :ment18, on the body ofthe valve :for' limiton the diaphragm, and'encircling the perfoingthe opening or upward movement thereration, saidv sleeve being provided with a 7 of, so that the said valve cannot bemoveid longitudinal series'of side openings of diffar enough to uncover any-opening. except ferent' diameters and forming a communicathe lowermost. The measure of the. vapor. ftion'between the inlet and the outlet, a valve ,movable in the sleeve for closing the perfotransmitting capacity of "the valve, under movement and a nut threaded into the casing and carration of the diaphragm, means for moving the valve, means for limiting the openin thereof for thepurpose specific rying the valve and of greater diameter than the sleeve.

A device of the class described comprising a casing having an inlet and an outlet at right angles to each other, a sleeve encircling the inlet, and having a longitudinal series of side openings of ,difi'erent sizes-communicating wlth the outlet, said casing having a threaded openin through which the sleeve may be remove a nut closing the opening, a valve/movable on the sleeve and havin a stem passing through the nut and carrie thereby, and means for limiting the movement of the valve for the purpose speciv 4. A device of the class described, comprising a valve casing provided with inlet and outlet ports, a sleeve reversibl mounted in the casin and communicating y one end with one 0 said ports and provided with a longitudinal series of side openings of different areas communicating with the other of said ports, a valve movable in the sleeve for closing the port communicating with the end thereof, and means for limiting the movement of the valve to prevent it uncovering more than one opening.

5. A device of the class described, comprising a valve casing provided with an inlet and an outlet port at right angles to each, other, a sleeve removably mounted vin the ment with each other, a sleeve removably mounted in the casing and registering with one of the orts, and having a longitudinal with the other port, a va ve for-closing the sleeve, and means for limiting the movement series of di erent sized o enings registering.

of the valve to prevent the uncovering of more than one opening.

7'. A valve casing having an inlet and an outlet port, a reversible sleeve in the casing registering with one port and having a plurality of side openings of differentsiz'e registerin with the other port and a valve movable m the sleeve.
